Tikz 矩阵中缺少分隔线

Question

我正在尝试通过无边框节点在 Tikz 矩阵中创建一个空白行，并填充白色。但是这个节点像图片一样切断了前一行分隔线的一半。如果我更改关键节点（test-3-1）的高度，它会影响整行。该属性outer sep=\pgflinewidth不起作用。有什么方法可以添加空白行吗？

\documentclass[margin=5mm,tikz]{standalone}
\usepackage{tikz}
\usetikzlibrary{matrix}
\begin{document}
\tikzset{
    table/.style={
        matrix of nodes,
        row sep=-\pgflinewidth,
        column sep=-\pgflinewidth,
        minimum height=1em,%           This needed for alignment
        text depth=0pt,
        text height=1ex,
        nodes={
            rectangle,
            draw=black,
            align=center
        },
        every odd row/.style={%      This needed for working code
            nodes={fill=gray!20}
        },
        row 3 column 1/.style={
            nodes={fill=white, draw=none}
        },
    }
}
\begin{tikzpicture}
        \matrix (test) [table, text width=1em] {
            ~ & ~ & ~ & ~ \\
            ~ & ~ & ~ & ~ \\
            ~ &  &  &  \\
            ~ & ~ & ~ & ~ \\
        };
\end{tikzpicture}
\end{document}

在这种情况下，我认为您只需设置fill=none在第三行。

\documentclass[margin=5mm,tikz]{standalone}
\usepackage{tikz}
\usetikzlibrary{matrix}
\begin{document}
\tikzset{
    table/.style={
        matrix of nodes,
        row sep=-\pgflinewidth,
        column sep=-\pgflinewidth,
        minimum height=1em,%           This needed for alignment
        text depth=0pt,
        text height=1ex,
        nodes={
            rectangle,
            draw=black,
            align=center
        },
        every odd row/.style={%      This needed for working code
            nodes={fill=gray!20}
        },
        row 3 column 1/.style={
            nodes={draw=none,fill=none}    % <------- here
       },
    }
}
\begin{tikzpicture}
        \matrix (test) [table, text width=1em] {
            ~ & ~ & ~ & ~ \\
            ~ & ~ & ~ & ~ \\
            
           ~ & & & & \\
            ~ & ~ & ~ & ~ \\
        };
\end{tikzpicture}
\end{document}
